When I try to save I get the message "One or more validation errors occured" and it flags this validator with the message the value for upperBound must be greater than lowerBound. To get around it I have to actually specify the lowerBound
as 050 instead of just 50. Last time I checked I thought 50 was less than 499 but maybe I'm going crazy!

I have a work around so it is not critical but I wanted to let the dev team know just in case someone else hits it.
